Electronic Structure
Get information about how electrons behave and how they are organized around atoms and ions. Learn about quantum numbers, magnetism, the Auflau Principle, the Pauli Exclusion Principle, and Hund's Rule.
Aufbau Principle and Electronic Structure
Stable atoms have as many electrons as they do protons. How do these electrons orient themselves around the nucleus? They fill their electron orbitals by the aufbau principle.

Quantum Numbers and Electron Orbitals
Chemistry is mostly the study of electron interactions between atoms and molecules. Understanding the behavior of the electrons in an atom is an important part of understanding chemical reactions. Electron orbitals depended on three properties: the amount of energy, angular momentum and magnetic moment of the individual electron.

What Do s, p, d, and f Mean?
s, p, d, and f are orbital names that stand for sharp, principal, diffuse, and fundamental. This summary tells more about orbitals and electronic structure.
